Abstract
A circuit arrangement having an input arranged to receive an input signal (U20) and an output for providing an output signal (U22). The circuit has an overall transfer function defined as the ratio between the output signal and the input signal and which is obtained by adding individual transfer functions of at least two different amplifiers with different slopes in their linear ranges and/or different limit values in their saturation ranges and/or different zero points alternately with positive and negative signs in a manner such that, at least partly, it corresponds substantially to a function of at least the third degree. This circuit arrangement generates, in a simple manner, an overall transfer function of at least the third degree, which can be used advantageously, for example, for the compensation of the temperature-verses-resonant-frequency characteristic function of a quartz crystal.
